DICK B. WILLIAMS, OF NEW oRLEANs, LoursrAN ASSIGNOR or oNn-srx'rn ro WILLI M F. WALL, on NEW YORK, N. Y., AND ONE-SIXTH 'ro cLAnENcE r. LAND- BETH, 0F PHILADELPHIA, PENNSYLVANIA.

TYING DEVICE FOR BUNDLING PURPOSES.

New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Tyin Devices for Bundling Purposes, of whic the following is a specification.

The present inventlon relates in general to devices for bindin bundles of laths, staves, lumber, and the ike, with wire drawn from, a continuous reel, and the invention has more particular relation to a novel and advantageous means for severing the wire and twisting the ends thereof.

The object of the invention is to provide a wire cutting and twisting mechanism which is very simple and inexpensive in its construction, which can be readily applied to any of the bundling machines in'common use, and; which will act in a positive and reliable manner to sever the wire and twist A theends thereofsecurely together so as to bind the bundle with the'wire.

A further object of the invention is the provision of a device of this character which is very quick in its action and will enable an operator to bind a large number of bundles in a comparatively short period of time,

With these and other objects in view, the invention consists in certain combinations and arrangements of the parts as-will more fully appear as the description proceeds, the novel features thereof. being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following descri tion and accom an in drawin s in which Figure 1 is an end view of a conventional form of bundling machine havin the improved wire cutting and tw-istin eviee applied thereto. Fig. 2 is a top p an view of the wire cutting and twisting device. Fig. 3 is a bottom view of the same.

Fig. 5 is a side viewof the device, portions being broken away, and Fig. 6 is an enlarged detached perspective view of the rotary cut-ting and twisting head.

to in 'the following description and indicated in all the views of the drawings by the same reference characters.

For the purpose of illustration the invention has been shown and will be described as employed in connection with a machine for bundling laths or the like, although it will be understood that the invention can also be employed wherever such a device would be desirable. I

The bundling machine comprises a frame 1 having a pair of oppositely disposed bundling arms 2 mounted thereon, the usual mechanism bein provided whereby the bundling arms can e operated through the medium of a foot lever 3. A reel 4 of wire is shown as mounted upon one side of the bundling machine toward the base thereof,

and the wire which is drawn from this reel passes between a pair of guide rollers 5 upon one of the bundling arms 2.

The wire cutting and twisting mechanism is designed to be permanently mounted in convenient relation to the bundles" of laths or other material to be bound, and in the present instance is shown asmounted upon one of the bundling arms 2. This device comprises a base plate 6 which has one end thereof rigidly secured in some suitable manner as by means of the screws 7 to one of the bundling arms 2, the opposite end of the base plate being provided upon opposite sides thereof with wire receiv'i slots 8. These slots 8 are shown as arranged in substantial alinement with each other, and a shaft 9 extends through the base plate and is journaled therein at an intermediate point between the inner ends of the slots. A rotating head 10 is rigid with one end .of the shaft 9 and bears against one side of the ,base plate 6, while an operating handle 11 'is provided in opposite ends thereof with wire receiving slots '13 which are designed utilized for securing the to be turned into registry with the wire re- 1 ceiving slots 8 of the base plate 6. The inner ends of the slots 13 incline downwardly in opposite directions toward each other so that the said slots almost meet at the bottom of the head, while at the top of the head the rotation of the handle while the device 7 they merely have a depth corresponding to the depth of the wire receiving slots 8 of the base plate. Intersecting the wire receiving slot 13 at each end of the rotating head and arranged in a plane at substantially right angles to the plane of the said slot is a slot 14 within which a retaining aw 15 is mounted. These retaining jaws are carried by spring strips 16 applied to the exterior of the head 10 on opposite sides thereof, and the inner ends of the jaws project into the wire receiving slots 13 so as to bear yieldingly against the wire and hold the same against accidental displacement.

For the purpose of enabling the rotating head 10 to be quickly turned into such a position that the slots 13 therein register with the slots 8 of the base plate, a depression 17 is provided in the top of the base plate for engagement with a spring pressed plunger 18 carried by the handle 11. The end of the plunger 18 is rounded and the sides of the depression 17 are inclined so that the handle can be turned in either direction byca-pplying force thereto, although it will be held securely against accidental turning. It will also be observed that the sides of the base plate 6 are beveled at 19 so that the plunger 18 will not engage the edges [of the base plate and interfere with is in operation.

Intthe operation ofcthe device, the lathe or other material are compressed in the usual manner by the bundling machine and a suit able length of wire drawn from the reel 4. The handle 11 having been turned into such a position that the wire receiving slots of the rotary head are in alinement with the wire receiving slots of the base plate and the plunger 18 in engagement with the depression 17, the wire is inserted in the slots 8 and 13 upon the far side of the device and then passed around the bundle, the free end of the wire being inserted in the slots 8 and 13 upon the inner side of the device. The wire is thus crossed between the cutting and twisting device and the bundle and the initial movement of the handle causes the rotary head 10. to act as a shear in connection with the base plate 6 and cut off or sever the.

' wire, the said wire being held against accidental displacement from the slots 13 by means of the spring actuated retaining members 15. The continued rotary' movement of the head 10 brought about through the me dium of the handle 11 operates to twist the ends of the wire, as is more clearly shown in Fig. 4. As the wire is twisted the ends thereof are withdrawn from-the rotary cutting and twisting head, so that by rotating 7 the handle 11, the wire is first severed, then twisted, and finally discharged from the device. However, the weight of the bundle would act to withdraw the extremities of the wire from the device as soon as the bundle had been released through the medium of the treadle 3.

A very essential feature of the present invention resides in the fact that the wire is cut off or severed before it is twisted, since the ends of the wire are then perfectly free and can be twisted with greaterease and facility than is the case where the wire remains connected to the reel until after the twisting operation. r

A further very important feature of the invention resides in the fact that theoperator or attendant has nothing to do but merely to turn the handle, this one movement acting as has been previously described to sever the wire, twist the same, and discharge it from the device. It will thus be obvious that the amount of time consumed in binding a bundle of laths or the like is much less than where the operator must first turn a crank to twist the wire, and then operate an independent mechanism for cutting the wire. 1

'It will be observed that a detail of practical importance in the construction of this. device is that of providing the rotating head 10 with the diagonally opposite terminal projections 25 which act as guiding abutments to insure quick and accurate in sertion of the wire in the opposite slots.

Having thus described the invention, what I claim as new and desire to secure by LettersPatent, is
